| Abstract |
This paper studied the effects of increased carbon (C) and nitrogen (N) supplementation in pond production of Artemia franciscana cysts in southern Vietnam. Pig manure and tapioca were used to supplement the natural food of Artemia in the ponds at a fixed C/N ratio 10. Addition of pig manure and tapioca at a standard rate (0.210 kg ww and 0.319 kg dw pond-1 day-1, respectively) was used as control. Increasing amounts of supplementation (110, 115, and 120 % of the control) were applied in three treatments. During the 6-week culture period, extra C and N supplementation resulted in a better growth, faster maturation, and higher fecundity of Artemia when compared to the control. Total cyst production was the highest (9.96 kg ww ha-1) at the supplementation level 10 % higher than the control; the lowest cyst production was found in the control (2.84 kg ww ha-1). Increasing the supplementation of C and N at levels 110, 115, and 120 % of the control at C/N ratio 10 may have stimulated the formation of bioflocs in the hypersaline Artemia ponds and helped to improve conditions for increasing cyst yields. |
